VALVE STRUCTURE.

Application led June 5, 1925. Seria-l' Nic. 35,071.

The present invention relates to valve structures; and its object is, generally, to provide such a structure improved in various respects and particularly adapted for use inbath apparatus wherein hot and cold water in desired variable proportions are used.

This general object and any other and more specific objects hereinafter appearing are attained by, and the invention nds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which:

Figure 1 is a face view of a valve structure ;v

Y Figure 2 is a transverse sectional viewofl the, same taken on line 2-2 of Figure 1, certain fragmentary parts thereof however being shown not sectioned; y

Figure 3 is a side view of the main portion of said structure, the closing caps and operating' handle being'removed; p

Figure 4 is a side view ofthe same, the valves and their carrying and operating means being removed;

Figure 5 is a view of the valves and their carrying and operating means ;V

Figure 6 is a vface view of said structure with its supply pipes and dischargepipe;` and Figure 7 is arview in perspective of a.

rotatable element vhaving. valve-operating.'

cams.l l v lin the accompanying drawings, apvalve structure-having supply pipesu and a'discharge pipe fitted with a spraying nozzle is shown. Thisstructure comprises a body portion, a casting 1, containing a mixing chamber 2 having an outlet 3 to its discharge pipe 4 terminating in the spraying nozzle 5, and inlets 6, 7 from the hot water supply pipe 8 and the cold water supply pipe 9 respectively. These inlets are preferably threaded at 10 to receive threaded valve seat members 11 having openings 12 therethrough comprising a central portion 13 and fluid passages 14 radiating therefrom, these valve seat members having valve seats 15. vA. member, the plate 16, is detachably and removably mounted on the body 1 inside the chamber 2 in such manner that it one interrelative position, as by the screws 17 and 18 passing therethrough and threaded in the inwardly-extending lugs 19, 20' respectively of the body 1, the openings through said member 16 for the screws 17,r

being' spaced further apart than are the openingsfor the screws 18. Y

An element, the plate 21, is rotatably mounted on the member 16 at 22 and carries the spindle 23 extendingthrough the cover of chamber 2 (which cover is secured removably to the bodyl 1l -by screws 26), the spindle then extending' through thedetachably` mounted outer cap Y27 of the structure and being furnished with an operatinghandle 28 having afpoi-nter 29L directed by the turning of said handle to suitable indicating marks, as' the' `words Cold-to-Hot displayed on theouter surface of said cap. Y

This element vor plate"2`1ihasycams, in-

dicated generally 30, 31, extending outward'-V ly and operating `by' the turningv of the ele-` ment 2l by its handle to open, or'permit the closing of, the puppet valves 32, 33I slidably carried at 34, 35y by the member 161' and springpressed at 36 into seating4 position 4on the valve seats 15 respectively. -The' stems" 37y of these valves extend through arcu'ate openings 38 'inf the element 211 and are threaded at 39 to receivegnuts 40, which preferably have a plurality of axially-spaced openings 41, so that a cotter` pin 42 maybethrust through any of said openings and into the aperture 43 extendingl transversely of the valve stem to secure the nut against. turni-ng thereon.'v rlhese nuts may be tight;- ened or loosened to "adjust the positionoff lthe valves' 3'-, 33 ,relativelyto their seatsJ 15` respectively; i

Each of the cams and 31 comprises a pair of arcuately-disposed parallel cam surfaces 44 and 45, disposed at the opposite sides of the respective openings 38. Inasmuch as the valves stems 37 pass through these'openings 38 and their nuts bear at their opposite sides on the members 44, 45 of these pairs respectively, it will be seen that the lifting or opening operation of each pair 44, 45 on the valves is such that the valves stems have no tendency to bind in their sliding movement in the openings 34, in -which they bear. In order to minimize the friction of these nutsl on the cams, said pairs 44, have inwardly-inclined adjacent edges on which the nuts bear; or equivalent thereto, the nuts themselves or both the nuts and said pairs of cam members may have such inclined bearing edges' as shown. The inner ends of the valve stems are threaded as shown to receive detachable extension members 51 bearing in the central portions 13 of the openings 12.

The member 16 carrying the valves has an arcuately-disposed groove 52 with end stops 53, and the rotatable element 21 has a lug 54 engagingin said groove5 so that said member and element cannot be assembled in any interrelative position lother than that in which the cam 30 will operate the hot water-controlling valve 32 and the cam 31 will operate the cold water-controlling valve 33.

The cam 30 for operating the hot watercontrolling valve 32 rises inclinedly an'd the cam 31 for operating the cold water-controlling valve 33 rises at 60 and then falls at 61 inclinedly as Vseen in Figure 7, so that the cold water-controlling valve may beincreasingly opened and then closed during the continued opening movement of the hotwater-controlling valve.

The invention being intended to be pointed Out in the claims, is not to be limited to 0r by 'details of construction of the particut lar embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. In a structure of the character described: a body containing a chamber having an outlet and inlets provided with valve seats.; a member carrying puppet valves seating on. said seats; means rotatable on said member and engaging the valves for operating the same; the body and said member having registering means whereby they may be detachably connected in one interrelative position only.

2. In a structure of the character described: a rotatable element having an opening and a pair of arcuately-disposed cams at the openings opposite sides and having their faces extending transversely to said elements axis; a valve having a stem eX- tending through-the opening and bearing on the cams in said elements valve-operating rotative movement. n Y

3. In a structure of the character described: a rotatable element having an opening and a pair of arcuately-disposed cams at the openings opposite sides with inwardly-inclined adjacent edges; a valve having a stem extending through the opening and bearing on said edges in said elements valve-operating rotative movement.

1. In a structure of the character described: a rotatable element having an opening and a pair of arcuately-disposed cams at the openings opposite sides; a waive spring-pressed to seating position and having a threaded stem extending through the. opening provided with a nut bearing on the cams in said elements valve-operating rotative movement.

5. In a structure of the character described: a rotatable element having an opening and a pair of arcuately-disposed cams at the openings opposite sides; a valve springpressed to seating position and having a threaded stem extending throughvthe opening provided with a nut bearing on the cams in said elements valve-operating rotative movement, the valve stem having a transverse aperture and the nut having a plurality of axially-spaced openings, the socket and any of said spaced openings registering therewith being adaptedvto receive acotter pin. Y

6. In a structure of the characterdescribed: a body containing a chamber having an outlet and inlets provided with valve seats; a member carrying puppet valves seating on said seats and having an arcuately-disposed groove with end-stops; means detachably mounted rotatably on said member for operating the valves and having a lug engaging in the groove.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 27th day of May, 1925.
